Meta-analysis: the prophylactic use of tranexamic acid to reduce blood loss during caesarean delivery.

Introduction: The 2022 national guideline on The Prevention and Management of Primary Postpartum Haemorrhage (PPH) recommended consideration of prophylactic tranexamic acid (TXA) for women who are at high PPH risk undergoing caesarean section (CS). This meta-analysis reviews the basis for this recommendation.

Bio-computational modeling, POM analysis and molecular dynamic simulation for novel synthetic quinolone and benzo[d][1,3]oxazine candidates as antimicrobial inhibitors.

The current study offers a metal-free, direct, and successful synthesis technique for a new series of quinolinone and benzo[d][1,3]oxazine, along with an assessment of their biological activities. Heteroannulation of anthranilic acid with carbonyl-containing chemicals (aroyl pyruvate, ethyl acetoacetatete, maleic anhydride, and ethyl cyanoacetate) resulted in the desired quinolones and benzo[d][1,3]oxazines. This technique introduces a number of fundamental breakthroughs in organic synthesis, including metal-free catalysts, smart reaction conditions with column purification, and a wide functional scope.

Comparison of first-line chemotherapy regimens in unresectable locally advanced or metastatic pancreatic cancer: a systematic review and Bayesian network meta-analysis.

Background: In advanced pancreatic ductal adenocarcinoma (PDAC), first-line chemotherapy is the standard of care. Due to the absence of head-to-head comparisons in clinical trials, we performed this systematic review and network meta-analysis to compare treatment options for PDAC in terms of their efficacy and toxicity.

Methods: PubMed, the Cochrane Central Register of Controlled Trials, Embase, and oncological meetings websites were searched until Nov 15, 2023.

Evolution of heart transplant donor characteristics in the 21 century: A United States single center's experience.

Despite a record setting number of heart transplants performed annually, the national donor shortage continues to plague transplant teams across the United States. Here we describe the barriers to adaptation of numerous "non-traditional" orthotopic heart transplant donor characteristics including donors with hepatitis C virus, those meeting criteria for donation after cardiac death, donors with coronavirus disease 19 infection, donors with the human immunodeficiency virus, and grafts with left ventricular systolic dysfunction. Our center's objective was to increase our transplant volume by expanding our donor pool from "traditional" donors to these "non-traditional" donors.

New Evidence From Census 2020 on the Residential Segregation of Same-Sex Households: A Research Note.

The 2020 decennial census provides new insights into the demography of same-sex households and can shed light on ongoing debates in urban and gayborhood studies. Although the U.S.
